I created a new functions app in VS2015 using the instructions here:

https://blogs.msdn.microsoft.com/webdev/2016/12/01/visual-studio-tools-for-azure-functions/

I selected "ServiceBusTopicTrigger - C#" as the template, and populated it with the relevant details (topic name, subscription name, SB connection string). I selected a meaningful name for the function. I haven't changed anything else. When I run the function, I get this error:

function.json looks like this:

{
  "disabled": false,
  "bindings": [
    {
      "name": "mySbMsg",
      "type": "serviceBusTrigger",
      "direction": "in",
      "topicName": "evohome-data",
      "subscriptionName": "test-functions",
      "connection": "Endpoint=sb://<host>.servicebus.windows.net/;SharedAccessKeyName=functions-access;SharedAccessKey=<key>",
      "accessRights": "Manage"
    }
  ]
}

and run.csx looks like this:

using System;
using System.Threading.Tasks;

public static void Run(string mySbMsg, TraceWriter log)
{
    log.Info($"C# ServiceBus topic trigger function processed message: {mySbMsg}");
    
}

You can't use a service bus connection string directly in function.json. You need to add a connection string name, and set the value in AppSettings.json.

Yeah, I discovered that. When you create the same function using the same template directly in the function app on the website, it automatically creates application.json and creates the reference for you - however when using the template within visual studio there is no application.json by default, and it doesn't automatically create the reference.
